OPTION AIR-D4 4-Channel Amplifier

Massive sound upgrade: The OPTION AIR-D4 is a powerful 4-channel Class-D power amplifier that breathes new life into your vehicle speakers. Enjoy significantly more dynamics, brilliance and enormous volume reserves compared to operating directly on the standard radio.

Ultra-compact design: Thanks to the extremely small dimensions (micro format), this amplifier can be installed almost anywhere in the vehicle. It fits easily behind the dashboard, glove box or under the seat - ideal for modern vehicles with limited space.

Perfect for original radios: With built-in high-level inputs and the auto-turn on function, the power amplifier is optimised for easy integration into factory installations. A separate remote cable is not required as the amplifier detects the signal directly.

Versatile 4-channel configuration: Take full flexibility: Power your front and rear systems simultaneously, or bridge two channels to power a front system and an additional subwoofer with powerful power.

High-efficiency Class-D technology: The modern digital circuit guarantees maximum performance with minimal heat generation and low power consumption. This ensures a permanently stable sound quality and protects the on-board electronics of your vehicle.
